New aftershock hits NZ families
An aftershock has rattled buildings in the earthquake-ravaged city of Christchurch, New Zealand. No serious damage or injuries have been reported.
The US Geological Survey said the 5.5-magnitude quake struck 14 miles west of Christchurch at a depth of just under two miles.
Christchurch has been rocked by scores of aftershocks since a devastating earthquake struck the city in February, killing 181 people.
The February quake was New Zealand's most expensive natural disaster, costing an estimated e8.35bn.
The latest quake knocked items off shelves in shops, but officials say there have been no reports of serious damage or injuries.
